M7 Low Distortion Lens Core Highlights

• Ultra-Low Distortion — Distortion below 1% helps maintain more accurate image geometry for applications where excessive image deformation can affect visual analysis.
• 2.9mm Fixed Focal Length — Provides a 75° diagonal field of view for broad coverage within a compact optical package.
• Compact M7×0.35 Mount — The miniature M7 interface is suitable for space-constrained camera modules and embedded imaging devices.
• 1mm BFL — The short back focal length supports integration into compact optical assemblies.
• Integrated IR Cut Filter — The 4P optical construction includes an IR cut filter for visible-light imaging applications.
• Fixed F2.8 Aperture — Provides a stable optical configuration for compact camera systems.

M7 Low Distortion Lens Applications

This M7 low distortion lens is designed for compact imaging applications where image geometry is more important than extreme field-of-view coverage. Its <1% distortion makes it particularly different from conventional fisheye and ultra-wide lenses, providing a more natural image shape while retaining a 75° diagonal field of view.

Designed for compact low-distortion imaging applications.

Compact Machine Vision

The low distortion characteristic makes this lens suitable for machine vision systems that need to capture objects with relatively consistent geometric proportions. It can be considered for inspection, positioning, object recognition, and visual monitoring where excessive barrel distortion could affect image interpretation.

The compact M7×0.35 mounting interface is useful for embedded machine vision modules where available installation space is limited.

Embedded Vision

The combination of a miniature M7 mount, 1mm BFL, and compact optical design makes this lens suitable for embedded camera systems. It can be integrated into small imaging devices where both optical performance and mechanical dimensions need to be considered.

Potential applications include compact inspection cameras, embedded vision modules, smart devices, and specialized imaging equipment.

Robotics Vision

In compact robotics vision modules, controlled distortion can be beneficial when the captured image is used for object recognition, positioning, or visual analysis. The 75° diagonal field of view provides useful scene coverage without the severe geometric deformation associated with fisheye optics.

Smart Monitoring

The 2.9mm focal length provides broad scene coverage for compact monitoring cameras, while the low-distortion optical design helps maintain a more natural image geometry.

The integrated IR cut filter makes this lens suitable for visible-light camera systems that require infrared wavelengths to be filtered from the imaging path.

Why Choose a Low Distortion Lens?

Field of view and distortion should be considered together when selecting a compact camera lens. Extremely wide-angle and fisheye lenses can provide greater coverage, but they can also introduce substantial geometric deformation.

This 2.9mm M7 lens takes a different approach. With a 75° diagonal field of view and distortion below 1%, it provides useful scene coverage while maintaining much more controlled image geometry.

This characteristic can be beneficial when straight lines, object proportions, or spatial relationships need to remain visually consistent.

Lens Selection Considerations

Before selecting this lens, confirm that the camera uses a 1/4″ image format and that the mechanical design supports an M7×0.35 mount.

The 2.9mm focal length provides a 75° diagonal FOV, while the 0.2m minimum object distance makes the lens suitable for relatively close imaging applications.

The 1mm BFL is also an important mechanical parameter when designing the camera housing and sensor-to-lens optical assembly.
